一、考慮其測(cè)量物質(zhì)的介質(zhì)問(wèn)題。也就是說(shuō)，其參考的標(biāo)志是會(huì)考慮測(cè)量介質(zhì)流速、儀表量程及口徑大小等。還需要來(lái)測(cè)量環(huán)境，挑選一個(gè)適合的測(cè)量環(huán)境，這所測(cè)量出來(lái)的結(jié)果具有一定的說(shuō)服力。 </p> <p> 二、一定要注意雷達(dá)料位計(jì)在測(cè)量上是否精細(xì)，這將主要是由于雷達(dá)料位計(jì)的精度等級(jí)與功能等級(jí)。在測(cè)量時(shí)，還會(huì)依據(jù)測(cè)量的場(chǎng)所、選擇精度等級(jí)不一樣的產(chǎn)品，從而做出非常精細(xì)的測(cè)量結(jié)果。所以當(dāng)你在使用時(shí)，自然需要考慮環(huán)境，從而做出精細(xì)的選擇。 </p> <p> 三、當(dāng)然選購(gòu)雷達(dá)料位計(jì)也是要將品牌考慮在內(nèi)，一些大品牌無(wú)論在技術(shù)上，還是在售后上，都是有一定保障的。淮安專業(yè)生產(chǎn)導(dǎo)波雷達(dá)料位計(jì)廠家因?yàn)?6GHz高頻雷達(dá)料位計(jì)方向性好，在很多惡劣工況下，可通過(guò)簡(jiǎn)單隔離，將雷達(dá)料位計(jì)裝在容器外進(jìn)行測(cè)量。</p><div

style="text-indent:25px">安裝應(yīng)注意的問(wèn)題:（1）當(dāng)測(cè)量液態(tài)物料時(shí)，傳感器的軸線和介質(zhì)表面保持垂直；當(dāng)測(cè)量固態(tài)物料時(shí)，由于固體介質(zhì)會(huì)有一個(gè)堆角，傳感器要傾斜一定的角度。（2）盡量避免在發(fā)射角內(nèi)有造成假反射的裝置。特別要避免在距離天線近的1/3錐形發(fā)射區(qū)內(nèi)有障礙裝置（因?yàn)檎系K裝置越近，虛假反射信號(hào)越強(qiáng)）。若實(shí)在避免不了，建議用一個(gè)折射板將過(guò)強(qiáng)的虛假反射信號(hào)折射走。這樣可以減小假回波的能量密度，使傳感器較容易地將虛假信號(hào)濾出。（3）要避開進(jìn)料口，以免產(chǎn)生虛假反射。（4）傳感器不要安裝在拱形罐的中心處（否則傳感器收到的虛假回波會(huì)增強(qiáng)），也不能距離罐壁很近安裝，比較好安裝位置在容器半徑的1/2處。（5）要避免安裝在有很強(qiáng)渦流的地方。如：由于攪拌或很強(qiáng)的化學(xué)反應(yīng)等，建議采用導(dǎo)波管或旁通管測(cè)量。雷達(dá)料位計(jì)非常便于現(xiàn)場(chǎng)工作人員的觀察，能夠?qū)崟r(shí)監(jiān)控指定儲(chǔ)罐內(nèi)物料的使用情況.泰州拋物面式雷達(dá)料位計(jì)生產(chǎn)廠家</p><p

雷達(dá)料位計(jì)適用于酸堿儲(chǔ)罐、漿料儲(chǔ)罐、固體顆粒、小型儲(chǔ)油罐。各類導(dǎo)電、非導(dǎo)電介質(zhì)、腐蝕性介質(zhì)。如煤倉(cāng)、灰倉(cāng)、油罐、酸罐等。1.雷達(dá)料位計(jì)安裝有何講究？NIVELCO雷達(dá)料位計(jì)對(duì)于安裝空間有一定的要求注意介質(zhì)的介電常數(shù)，并依據(jù)介電常數(shù)的大小選擇適合的型號(hào)2.雷達(dá)料位計(jì)兩線制和四線制的區(qū)別是什么雷達(dá)料位計(jì)兩線制的要比四線制的價(jià)位上便宜好多，并且MONITOR的四線雷達(dá)量程再60m左右，NIVELCO兩線制雷達(dá)量程24m左右，再就是四線的24v和4-20MA用不同的端子，兩線的是共用端子。四線有雙桿探頭，兩線的沒(méi)有。3.雷達(dá)料位計(jì)測(cè)量誤差有哪些？MONITOR雷達(dá)料位計(jì)的電磁脈沖以光速沿鋼纜或探棒傳播，當(dāng)遇到被測(cè)介質(zhì)表面時(shí)，雷達(dá)料位計(jì)的部分脈沖被反射形成回波并沿相同路經(jīng)返回到脈沖發(fā)射裝置，發(fā)射裝置與被測(cè)介質(zhì)表面的距離同脈沖在其間的傳播時(shí)間成正比，經(jīng)計(jì)算得出液位高度。所以影響測(cè)量誤差的是介質(zhì)，但是導(dǎo)波雷達(dá)料位計(jì)的技術(shù)優(yōu)勢(shì)：雷達(dá)料位計(jì)對(duì)液體、顆粒及漿料連續(xù)物位測(cè)量。測(cè)量不受介質(zhì)變化、溫度變化、惰性氣體及蒸汽、粉塵、泡沫等的影響。鎮(zhèn)江拋物面式雷達(dá)料位計(jì)哪家品牌好</p></p><br
